Explanation
Two reasons an admin should choose an Event over a Trigger when it comes to building out a solution are:
Events are asynchronous. This means that events are processed in the background, without blocking the main execution thread. This can improve the performance and user experience of the solution, as well as avoid governor limits and timeouts.
Events do not participate in a transaction scope. This means that events are independent of the transaction that publishes them, and they do not affect the rollback or commit behavior of the transaction. This can avoid unwanted side effects and errors in the solution, as well as decouple the logic from the data.

Explanation
Two statements about the Order Summary object that are accurate are:
It does not exist without the original Order object. An Order Summary is a record that represents the financial summary of an order that is received from anexternal system, such as B2C Commerce or B2B Commerce. An Order Summary has a master-detail relationship to the Order object, which means that it cannot exist without its parent Order record.
It is read-only for financial order data. An Order Summary contains financial order data, such as total amount, tax amount, discount amount, etc., that are populated from the external system when the order is created. These fields are read-only and cannot be edited in Order Management.

Explanation
The best place for a service agent to go first to view process exceptions related to a specific Order is the Order Record - Process Exception Details Tab. This tab shows a list of process exceptions that occurred during the order lifecycle, such as errors in payment authorization, inventory allocation, fulfillment location assignment, etc. The service agent can use this tab to identify and resolve the issues that affect the order processing.
